| Clouding can follow laser eye treatment
Laser-based vision correction, such as LASIK, usually results in greatly improved visual acuity, but occasionally it can be followed by a clouding in the center of the cornea and poorer vision. Fortunately, the corneal opacification resolves on its own within a matter of months, according to two ophthalmologists in Los Angeles, and the related vision problem is safely reversed with a repeat laser treatment. Dr Baris Sonmez from the David Geffen School of Medicine at UCLA and Dr Robert K Maloney from the Maloney Vision Institute describe their experience with what they term "central toxic keratopathy" following laser refractive surgery in the American Journal of Ophthalmology. The eye specialists note that such cases have been reported since 1998. To better characterise the condition, Sonmez and Maloney reviewed the charts and clinical photographs of 14 affected patients they had treated.
Medical and health tourism
2007-04-01 14:48:49 - Medical and health tourism is an international trend that many people join rest with different kinds of health and beauty procedures. SPA & Wellness Rest connected with treatment and prevention in health resorts is popular all over the world for many centuries. Resorts created in the Roman Empire based on baths that generally means SPA (sanus per aquam- health through water) still are flourishing and are very popular among tourists. There are English resorts, for instance Bath, German Baden- Baden, Czech .

Allegretto Wave Eye-Q granted wavefront-guided, mixed astigmatism ...
STERLING, Va. The U.S. Food and Drug Administration has approved wavefront-guided and mixed astigmatism indications for WaveLight's Allegretto Wave Eye-Q system, the company announced in a press release. The FDA approved the Eye-Q system for reducing or eliminating up to 7 D of spherical equivalent of myopia or myopia with astigmatism, with up to 7 D of spherical component and up to 3 D of astigmatic component at the spectacle plane. The system is approved for use on patients at least 18 years of age who have a documented stable manifest refraction defined as less than or equal to 0.5 D of preoperative spherical equivalent shift over 1 year preop, according to the release. Procedures performed using the system can also be done with a custom offset of 3 D to +1 D for sphere and 3 D to 0 D for cylinder, the release said.
